Tycho's rays Piccolomini and Rupes Altai. Pictures by astronomical telescope

In this article, I"ll give an example of how important is the phase of the Moon and how different looks the lunar landscape at just two days apart. In the photos above, the Moon was illuminated by the Sun 51%, more light than two days ago, when it was lit 32%.

At 51%, are observed other features of the Moon, such as the albedo which is spread on the surface of different craters, and, (see a long band of albedo crossing the Rupes Altai reaching Mare Nectaris). This is a ray of the crater Tycho, which is just 1123 km from Piccolomini.
